Abstract

In the present study, production of bioelectricity in microbial fuel cell developed with slaughter house waste fluid was enhanced by optimization of agarose salt bridge and electrode size. Agarose salt bridge was optimized by different percentage of agarose from 1%-3% with different sodium chloride concentration from 1%-3%. Graphite plates of different sizes (LXBXH) 4x4x0.3cm, 5x5x0.3cm, 6x6x.0.3cm, 7x7x0.3cm and 6x6x3cm were used. 1% agarose salt bridge with 3% sodium chloride produced maximum voltage and current, 560mV and 2.60mA respectively. Graphite plate of 6x6x3cm gave the maximum voltage of 620mV and 4.8mA after 7 days, when compared to other sizes of graphite plates.
